vThis invention relates 'to dryingapparatus, suchv as is used, for example, in household laundries and the like. More particularly, the invention relates to drying apparatus of cabinet form including an air heating chamber, a clothes drying chamber, suitable devices on which the clothes may be supported, and the necessary means for Vproducing proper flow or 'circulation of air through the drying chamber. i Y

The present application is a companion'to another application for drying apparatus, filed of even dateherewith, Serial No. 656,701. The invention ofthe present applicationrelates more particularly to a special form and arrangement of cabinet, and drying racks on which the 4clothes to bedried are supported, said racks being arranged torbe Yoset from each other in a directionparallel to the planes Vof the racks when they arein closed position in the drying chamber and lyiiigin substantially parallel relationwhen opened out perpendicularto the drying chamber, for the purpose of affording maximum access to all racks for loading vand unloading the same,

fsuch effects being obtained by-special arrangements of the racks and pivots therefor as more particularly described hereinafter.v

In the drawings, Fig; 1 is in 'partafront elevation, showing one of the cabinet vdoors open, andin part a broken out sectional elevation on the line 1-`-1,Fig.2; Fig. 2'is inpart Van end view from the right in Fig.'.1 andV in A'part a sectional elevation on the line 2'-'2, VFig. 1; Fig. 3 is a sectional plan view on approximately the "line 3`-3,Fig. 1;V Fig. 4 is a similar View on the line 1L- 4, Fig. 1; Fig. 5

is a detail sectional elevation onthe line 5 5,

` Fig.'1;and Figs. 6 and 7 are detail plan .views illustrating modied forms of drying racks."

Referring to the drawings the apparatus -comprises a suitable cabinet including an upper member 1 in which is a drying' chamber 2 closed Aby doors, andlbelow which is a lower member l having a heating'chamber y5, and whichjmember serves as a support for the upper member, beingseparated therefrom bya horizontal wall 6 provided with screenedA openings 7 and 8. Except ffor rdifferences hereafter described the constructionv and ar` rangement of this cabinet is similarto thatlof my companion application before referred to,

to which reference may behad for a more complete description where necessary. Said companion applicationA illustrates a gas In'tlie present heater for the air current. application, adapted especially where gas is unavailable for fuel, the heater is of electricv form, comprising a grate or kgrid'formed of longitudinally extending parallel. electrical heating elements 9 suitably connected in a circuit controlled by the switch 10. Air l' enters the lower casing member ythrough an Vinletrll controlled by a damper.f12, said air flowing to and through the chamber 5, being `diverted upwardly bythe deflectors or baffles 13 to cause it to pass through thespaces 14 between neighboring heating elements 9 and through the screened opening 7 to chamberv 2 in which it rises, followingthe general course of thearrows A, and Hows downwardly through the screenedopening 8 to a chain.

takenfup or absorbed by the air stream and carrie-dover andv around the-material to be dried. The How of air alongthe path described ispartly by convection, due tothe air current rising from` the heater, oi' may be more or less induced or accelerated by a suitable fanf 18 controlled by a switch 19, the velocity offlow being also capable of control i by damper 12, so as will bereadily understood.

I.' The materials to be vdried are .supported upon suitable'raclrs in the drying chamber 2.

These raclrs,tof which any- `number may beV used, are located in parallel vertical planes` and arearranged so as to be capable of swinging out vto an open position perpendicular to the general planes of the racks when closed. The rear raclr is xed or stationary, consisting of horizontal members 2O suitablysupported inv the casing.y y The three front racks are of special form and arrangement. Each of these racks comprises two vvertical side members 21, formed for example, ofinetal pipes` connected by wooden horizontal cross bars V2K2,

i the i same direction.

the latter being split attheir ends, as at 23, and provided with openings to receive the pipes 9.1, the parts being attached by clamp'- ing screws or bolts 24 which firmly clamp the ends of the Wooden bars tothe pipes. v One of the end pipes or bars of each rack 1s provided at top and bottom with fittings or arms 25 carrying vertically extending pivot mem-l bers 26 entering aligned openings in the rooi andlioor respectively'ofzthe drying chamben The upper of such pivots may be slightly nearer the door'opening than thelovver so that each rack has` a natural tendency to spring Vtoward open position or outwardly from the drying. chamber. It willbe understood that .as the racks are pushed back to theirclosed positions, shown, in full lines Fiend, pins 29 thereon ride up along the inclined edge of a suitable bracket 30 with slight rising motion Vof. theentire frame inthe drying chamber until the. pin reaches. itsseat in the recess, being *,releasably held thereby gravity.v f f The pivots for. the several racks may be arranged. in various ways. In Fig. l the pivots 26 are oltset fromthe median planes ofthe severalv racks .different distances, but-all 1n In other words, thearin for: the front `racl: is short and entends for- -.wardly,]while .the arm for the third rachis longer but also extends forwardly. Also, as shown inFig. 4, the several racks are oliset result they are offset or lie in spaced parallel arrangement when closed, and are also oiset but lie in closely neighboring parallelrelationk whenfopen, as shown in dottedlines,pFig.

so that the pivotsvare-offset or in stepped'relal tion in the planes of the racks, 'but not per pendicularly thereto.

Other arrangements are obviouslysuit'able forthe purpose. l Y
